Jan. 13 (Bloomberg) -- Emerging-market stocks advanced the
most in a month as commodity producers jumped after Indonesia’s
ban on mineral ore exports fueled speculation nickel supplies
will decline. The Jakarta Composite Index led world gains.

The MSCI Emerging Markets Index added 0.8 percent to
977.42, gaining for a second day. OAO GMK Norilsk Nickel, the
world’s largest producer of the metal, rallied the most in 13
months in Moscow, Nickel Asia Corp., which accounts for about a
third of Philippine output, climbed. Indonesia’s benchmark stock
index increased 3.2 percent for the biggest advance among 94
global indexes, while the rupiah rose the most in six weeks.

Commodity shares joined a rally in nickel after a ban on
mineral-ore exports took effect in Indonesia, the biggest
producer of the metal from mines. The ban is part of a wider
policy to boost state revenue by turning Indonesia from an
exporter of raw commodities into a manufacturer of higher-value
products. Emerging-market stocks also gained as worse-than-estimated U.S. jobs data last week eased concern that the
Federal Reserve will accelerate the pace of stimulus cuts.

“Indonesia’s ban on mineral ore exports is the best
possible scenario for nickel producers,” Vladimir Sergievskiy,
an analyst at Barclays Plc in London, said by phone today.
“It’s not an easy decision and many market participants didn’t
expect the ban to materialize. It cuts global supply and will
result in higher prices.”

Russian shares gained the most this year as Norilsk
increased 4.7 percent. The Czech PX Index capped the biggest
advance since October, while benchmark stock gauges in Poland
and Hungary added more than 1.5 percent.

The Jakarta Composite posted the biggest increase since
Sept. 19 as banking, property and construction shares rose amid
a strengthening rupiah. The currency gained the most since Dec.
2. Thailand’s stocks jumped to a two-week high on optimism Prime
Minister Yingluck Shinawatra’s proposal to initiate talks with
anti-government demonstrators will help ease political tensions.
Nickel Asia climbed 5.7 percent in Manila.

Infosys Rallies

India’s benchmark stock index rose the most in seven weeks
after factory output unexpectedly fell and U.S. jobs growth
slowed, easing concern that the nations’ central banks will
tighten monetary policy. Infosys Ltd. climbed, completing its
biggest two-day gain in three months. Oil & Natural Gas Corp.
increased for a third day, sending a measure of energy companies
to its steepest gain in four weeks. ICICI Bank Ltd., the
nation’s second-largest lender, rallied the most in a month.

The Shanghai Composite fell for a fourth day, as declines
for technology and consumer shares overshadowed a rally for raw-material companies. GoerTek Inc., an Apple Inc. supplier,
retreated to the lowest level since May. Aluminum Corp. of China
Ltd., known as Chalco, gained at least 7 percent in Shanghai and
Hong Kong after it estimated net income of 1 billion yuan ($165
million) in 2013.

The premium investors demand to own emerging-market debt
over U.S. Treasuries advanced two basis points, or 0.02
percentage point, to 320 basis points, according to JPMorgan
Chase & Co.
